The need for chemotherapy for trophoblastic tumour after evacuation of a hydatidiform mole was found to be significantly increased in patients taking oral contraceptives before normal human chorionic gonadotrophin (HCG) values were obtained. Oral contraception was also found to delay the fall in HDG excretion in patients not requiring treatment with cytotoxic drugs.
在获得正常的人绒毛膜促性腺激素（HCG）值之前服用口服避孕药的患者中，葡萄胎清宫术后滋养细胞肿瘤化疗的需求显著增加。研究还发现，口服避孕药会延迟那些不需要细胞毒性药物治疗的患者体内HCG排泄量的下降。
